Build 0.6

This week I mostly focused on restructuring code, and fixing some outstanding bugs. The LineRenderer issue has been fixed, and now I use a line instead to generate my custom level dependencies. In the future, I plan to scrap the line idea entirely in favour of custom visualizations like this:

In addition, I've added 5s and 6s to the animal roster!

Up for next week, I think I should implement the star system as a workaround for levels being a bit too hard - instead of forcing the player to find every last solution, just half of them will do.
